A source from Japan with a background in nuclear engineering describes this recent video filmed in Namie, Fukushima Prefecture:

Beta-ray cut-off characteristic graph

  • “Please watch this very interesting video. It shows that we can cut off much amout of beta-ray from Black Substance, with a few papers.”
  • “Of course, we know that the black substance’s beta-ray includes beta-ray from Cs-137 & Cs-134. However, the black substance has too much beta- ray, in comparison with that from Cs-137 & Cs-134 only.”
  • “We have not identified the source of this strong beta-ray, but it might be from Sr90 and some other beta nuclides.”

    I thought paper could only block alpha radiation.

    I thought beta required something like thick acrylic to be blocked.

    • gottagetoffthegrid

      a single sheet of paper will stop alpha. a thick stack will stop Beta. its not the substance, its the thickness and density that stop the various particles.

      depending on the energy in the beta particle, a different thickness of paper will be required. Im not sure how one would calibrate it. you'd need a clean sample of Cs 137/4 and Sr90.

      Relax all , United-we-fail Nations sez Japanese should't worry about high cancer incidents compared to Chernobyl .
      Not even if the population density in Japan far exceeds the area around Chernobyl … and they eat seafood , raw and irradiated , while their iradiated water accumulates and sets deposits in their cities and the ocean floor .

      BUT , we shall take the UN statement with a bucket of salt for the very Good reason of " How can you Trust and What can you say about a bunch of nations that bent-over and accept the Veto power of a handful " !! Eat your heart out Circle du Soleil , the UN is Real !

      U.N.: Post-Fukushima collective thyroid dose about 3.3 % the dose from Chernobyl


      " The health effects from the Fukushima nuclear accident are substantially smaller than those from the Chernobyl disaster , and the increase in cancer incidence in Japan will be negligible , according to a U.N. panel's estimates . "

        Are you for real, Mr. Jay? You should say one way or another. Your posts get a little bizarre regarding their intent. You're real or you are sarcastic. But it's getting to be less fun figuring it out. The topic itself is way too heavy.

        • Jay

          WeNotTheyFinally , why are you puzzeled , please tell me what is unclear in my post and I will explain .

          The above one mentioning UN has no mysteries , everyone knows the sham UN is … questions ?

          • Its Curtains

            I didn't find Jays comment confusing, however there are times I do. I think, though I could be wrong, that English is not his first language so there could be some things lost in translation. Also Jay, this is in no way meant to be insulting on my part.

    Not that it would affect my comfort level either way, but aren't alpha rays the ones that are stopped by a sheet of paper?

    • ALPHA: 20 TIMES the cell-damage

      Alpha radiation is dangerous when alpha-emitting radioisotopes are ingested (breathed or swallowed).

      This brings the radioisotope close enough to tissue for the alpha radiation to damage cells. Per unit of energy, alpha particles are at least 20 TIMES more effective at cell-damage as gamma rays and X-rays.

      Examples of highly poisonous alpha-emitters are radium, RADON, and polonium.

      • We Not They Finally

        That is a REALLY good point. People downgrade the potential damage of alpha. But if they are ingested, they can concentrate local damage and cause huge harm.

        • pinksailmatt pinksailmatt

          20x is the assumed average. Ranges from 10 to 1000x are possible. And as for Po-210 (remember the Russian Spy who died?)…Currently this is the only alpha emitting byproduct material available, as a NRC Exempt Quantity, which may be held without a radioactive material license. Got $120 bucks?

    • hbjon hbjon

      It's not like the paper didn't sustain damage in the collision.

  • TheBigPicture TheBigPicture

    Radiation from Fukushima Daiichi is leaking and spreading, still.

  • Lion76 Lion76

    How much is "blocked" if you inhale/ingest this mystery black substance?

    • We Not They Finally

      Anyone ingesting ANYTHING that is 140,000 CPM is in serious trouble!! Only 100 CPM is even considered "safe." This is 1400 times as lethal! And this is also not "new." Already found as far away as Tokyo a long while back.

      • Lion76 Lion76

        100 CPM is the low end of "unsafe" for "background" there are no safe levels of INTERNAL dose rates.

  • safelyiniowa safelyiniowa

    Remember the Russian ex-spy who was killed with an alpha emitter in his tea? I don't remember if it was Americium or Polonium.

  • We Not They Finally

    A lot of highly radioactive BLACK FUNGUS was found there, also in TOKYO. It is said to measure 170,000 [not a misprint] CPM, when only 100 is considered safe. This article says 140,000 CPM, but who is going to quibble abut certain death? Where is the info about HOW MUCH there is of this? It's NOT an anomaly. It's just one of countless samples.

    • drinkupdreamers drinkupdreamers

      This fungus was the FIRST thing I thought of, We.

    • lam335 lam335

      I thought some expert had said that the black stuff was probably some kind of "cyanobacteria."

      • Jebus Jebus

        Is that the same expert that said nuclear power plants probably can't blow up?

        • Fall out man!

          +1 Jebus!
          I think it might have been the head of Japanese health, Dr Yamashita who said it. He's the expert who claimed people who are cheerful and positive are unaffected by radiation! (then later in a private address to health professionals said that lie was just for the general public)

    Chernobyl? Fukushima? London? What does it matter? We are poisoning the whole planet. Please see this incredible article by award winning journalist and documentary film maker John Pilger:

    The dust in Iraq rolls down the long roads that are the desert’s fingers. It gets in your eyes and nose and throat; it swirls in markets and school playgrounds, consuming children kicking a ball; and it carries, according to Dr. Jawad Al-Ali, “the seeds of our death”.

    An internationally respected cancer specialist at the Sadr Teaching Hospital in Basra, Dr. Ali told me that in 1999, and today his warning is irrefutable. <b>“Before the Gulf war,” he said, “we had two or three cancer patients a month. Now we have 30 to 35 dying every month.</b> Our studies indicate that 40 to 48 per cent of the population in this area will get cancer: in five years’ time to begin with, then long after. That’s almost half the population. Most of my own family have it, and we have no history of the disease. It is like Chernobyl here; the genetic effects are new to us; the mushrooms grow huge; even the grapes in my garden have mutated and can’t be eaten.”<
    Pilger's article is <a href="">From Iraq a Tragic Reminder to Prosecute the War Criminals</a>.

    • J.

      Pilger is right as usual. The people of Iraq are victims of a horrendous war crime. There's an astounding documentary on YouTube about a German and an American who both suffered greatly from their efforts to document the damage done by uranium weapons. The German was an MD in Iraq for much of his career. If I can dig up the title I'll post it here. There are several other fine documentaries about DU weapons on YouTube. The facts are available for those willing to look.

    140000 cpm equals to 1.4 Sv/h. madness

    140,000 to 170,000 CPM.. yes.. it could be Cs-134 or Cs-137, no problem.

    You can get well over several CPM (500+) from straight KCl salt, Of which just 0.012%(1 in 8333) of the potassium is radioactive K-40 (half life 1.248 billion years)..

    Now substitute the Potassium with an atom of Cs-134(half life 2.06 years) which is 10 trillion times more radioactive.

    Or substitute it with Cs-137(half life 30.167 years) which is 638 billion times more radioactive.

    The human body typically contains 0.2% K, which is typical for most plant and animal life.. Roughly half of normal Internal exposure comes from the K-40 (which makes up 0.12%) component of all Potassium, resulting in count of 20 CPM or so measured 1" from human skin. (just from the K-40 component).

    Thus substituting 0.00000017% of the Potassium in the sample with Cs-134 will yield a biological sample that will radiate @ 170,000 CPM. 170,000 CPM count using Cs-137 will require replacement of just 0.0000025% of the Potassium.

    So.. yes.. that black organic sample could be just a moderately high concentration of radioactive Cs isotopes.. Nothing special here, except that most people vastly under-estimate the true nature of these radioactive isotopes humanity has unleashed into our biosphere.

    What they really need to do is measure the energy level of those beta decays using a Scintillation detector, those results would tell you what radioactive isotopes are in the sample and their…

    You might be puzzled because "We Not They Finally" probably didn't careful read your post. If one scans quickly, your post, one could be forgiven for misreading it.

    It is crystal clear to me that you (J) are using a literary method to belittle the UN report you provide the link for.

    When one reads the report, one understands your contempt.

    I suspect you posted when freshly angered by that report, and I certainly share that outrage, as I suspect "We Not They Anymore" will if they/we read it.

    ps We/they, please note that the "they" reference from Jay's post was referring to the Japanese populace, so all in all, it's clearly sarcasm, albeit employed while upset.

    I'm on dialup and can't view utube video, but the descriptions from the posts give the impression that whatever is radiated from the black substance is safely blocked by something as insignificant as a sheet of paper (or two). If it was heat radiation being blocked by the paper, at some (near) distance from the source it would ignite; my point being, because a sheet(s) of paper prevents the radiation from registering on the detection equipment gives me NO information about the many ways MY BODY can be impacted. And that's the scary part that should be discussed (in the utube video).
    I hope it is.

  • Why not talk of the upside of this increased radiation? Yes, some will get incredibly sick from the contamination and some will ultimately die. That is called unnatural selection. As our planet progresses towards its ultimate demise some 5 billion years from now, the background radiation will rise accordingly. Our Sun is the real danger here, with all of its filthy radiation. God, in his infinite wisdom has delivered us some "black material" so humanity can get a jump on the increased radiation.
    Only those special people that are intended to get to the end of this journey called Life on Earth, will get there. It is all so perfect.
